custom-data-attribute

I have a list here <ul id="demo2" data-name="demo2"> <li data-value="here">here</li> <li data-value="are">are</li> <li data-value="some...">some</li> <!-- notice that this tag is setting a different value :) --> <li data-value="initial">initial</li> <li data-value="tags">tags</li> </ul> Where each li item has a custom data attribute. On JQuery how would get all of the values of each li element which has an attribute of data-value? I want to get their value. but this code of mine doesn't seem to be working $('#view-tags').click(function(){ $('li[data-value]').each(function(){ alert($(this).data

On elements I can specify the data attributes as, e.g. <div data-widget-type="MyWidgetType1" data-property1="20" data-property2="test"> ... </div> I want to capture these in a class e.g. .MyClass1 { data-widget-type:"MyWidgetType1"; data-property1:"20"; data-property2:"test"; } <div class="MyClass1"> ... </div> Is there a way to specify data attribute values in CSS?

This is my method public Component SaveComponent([ValidateMetaFields] Component componentToSave) { ... } This is my custom attribute: [AttributeUsage(AttributeTargets.Parameter)] public class ValidateMetaFieldsAttribute : Attribute { public ValidateMetaFieldsAttribute() { // how to access `componentToSave` here? } } I am wondering is there a way to access componentToSave object from ValidateMetaFieldsAttribute ? I could not find any sample code or examples. No, attribute instances don't have any notion of the target they're applied to. Note that normally you fetch attributes from a target, so

I imagine this should be a pretty trivial task but using Firefox for Mac, 3.6.12 the following does not work: // assign data attributes $('.gallery li').each(function(i) { $(this).data('slide',i+1); }); // outputting an empty jQuery object console.log($('.gallery li[data-slide]')); // this does not work either outputting an empty jQuery object console.log($("[data-slide]")); using Firebug I can see that all the data-slide attributes including their numerical value are correctly attached to the li s and logging out: $('.gallery li').each(function(index) { console.log($(this).data()); });
